Preliminary study of efficacy of intravenous cisplatin plus oral etoposide in small cell lung cancer.
Twenty-three patients with small cell lung cancer were treated with combination chemotherapy consisting of Cisplatin at 100 mg/m2 given by 2 hours intravenous infusion on day 1 and oral etoposide 25 mg/caplet given twice a day for 21 days repeated every 28 days for 6 cycles. Of 23 cases, four cases were not evaluable due to early death (three of them died from febrile neutropenia). Median age of the patients was 59 years (range = 45-76 years). Five cases were female and eighteen cases were male. Median Karnofsky performance status was 70 per cent (range = 50-90%). Five cases were extensive disease and eighteen cases were limited disease. Of 5 extensive disease cases, 1 complete response (20%) and 3 partial responses (60%) were achieved. Of 14 limited disease patients, 1 complete response (7.1%) and 11 partial responses (78.6%) were achieved. Hematologic toxicities were severe causing three patients to die because of febrile neutropenia, nine cases (10.7%) had grade 3 and 4 neutropenia. Grade 3 and 4 anemia and thrombocytopenia were seen in 28.6 per cent and 8.3 per cent respectively. Median survival time of all cases was 7 months. Thus, the combination of intravenous cisplatin and prolonged administration of oral etoposide could be administered to small cell lung cancer patients with high response rate, however, because of its severe toxicities, special caution should be considered and the optimal duration of oral etoposide should be evaluated.
